Malnutrition

What is Malnutrition?

The World Bank data estimates that India has one of the worldís highest demographics of children suffering from malnutrition. About 30-40% of the worldís malnourished children live in India where one-third of the Indian population is believed to be malnourished.

The alarming condition has become a public health concern and the Government of India is increasing food subsidies to tackle the situation. According to Nobel prize winner for economics Angus Deaton, malnutrition in India is not just related to calorie intake, but Indiaís dependence on a carbohydrate-based diet with low protein and fat diet.

Malnutrition is a serious condition that develops due to inadequate or imbalanced intake of vitamins, minerals and other nutrients needed to maintain health and organ function. Malnutrition can be under-nutrition or over-nutrition. Under nutrition is the consequence of consuming an inadequate amount of nutrients and calories needed for the overall development and growth of body while over-nutrition results from overeating or consuming nutrients in wrong proportions; for example, following a diet with excess fat but limited proteins and vitamins.

What are the Causes of Malnutrition?Depending on the type of malnutrition, the related causes are as follows:

Poor dietary intake

Mental health problems such as depression or schizophrenia alter your mood and the desire to eat, leading to a poor appetite

Alcoholism: Alcohol contains calories which in turn can reduce the patientís desire to eat enough to supply the body with essential nutrients. Also, alcohol leads to damage to liver which is the storehouse of proteins and vitamins

Dementia is a brain disease that leads to a gradual decrease in the ability to think and remember and this affects a personís daily functioning. Patients often forget to eat meals for hours together

Economic status: Those who are poor are at risk of under-nutrition; on the other hand, those who have high socio-economic status are more likely to be over-nourished

What are the Symptoms and Signs of Malnutrition?Unintentional weight loss is considered as an initial sign of malnutrition. Signs and symptoms vary and depend on the causes. Following are the signs and symptoms of malnutrition.

Losing 5-10% of total body weight without exercise

Fatigue

Dizziness

Skinny or bloated

Brittle or spooned nails

Slow wound healing

Skin may be pale, thick, dry and bruise easily

Soft and tender bones

Joint ache

Visual disturbances

Anemia

Goiter (enlarged thyroid gland)

Muscle twitches

Loss of reflexes and lack of muscular coordination

Scaling and cracking of the lips and mouth

Malnourished children will be short and thin for their age and will have a weak immune system

How do you Diagnose Malnutrition?Malnutrition can affect people of all age groups and both sexes equally, from infants to adults to the elderly. Overall appearance, behavior, and body-fat distribution are manifestations of malnutrition that can alert your family physician to check the condition.

Blood and urine tests are done to measure the levels of vitamins, minerals, and other nutrients.

Nutritional assessment is done and determined by:

Comparing weight to standardized charts

At a later stage, X-rays are recommended to determine bone density and gastrointestinal disturbances.

Psychiatric assessment to identify disorders like depression, Alzheimerís, and anorexia nervosa that might be the cause for malnutrition.

How do you Treat Malnutrition?Treatment of malnutrition usually comprises of replenishing the deficient nutrient store and treating the symptoms as needed.

The underlying problem needs to be treated first. For example if a psychological problem like anorexia or depression exists, that condition needs to be attended to along with a nutrient-rich diet and supplements to compensate for the missing nutrition. A balanced diet plan that will restore adequate nutrition needs to be formulated.

A person who is unable to eat and absorb nutrients taken by mouth due to swallowing problems (e.g. mouth cancer) needs to identify alternate methods to meet the nutritional requirements of the body.

Parenteral nutrition is nutrition given intravenously directly into the blood in the form of a solution containing nutrients through a tube via a vein.

Enteral nutrition involves a tube that is inserted into the digestive tract via which nutrient-rich solution is passed directly through for maximal absorption.

A diet rich in fat, protein and carbohydrates along with adequate portions of vitamins A, B, C, D, E, K and vital minerals like iron and calcium needs to be fed to the patient to replenish depleted stores in the body.

What are the Complications of Malnutrition?An estimated 1.9 billion adults worldwide are overweight, 462 million are underweight. Forty one million children under the age of 5 years are overweight or obese, while 159 million are stunted and 50 million are wasted.

Common complications of malnutrition include a greater risk of developing infection, fatigue, weakness, bone ache, decreased bone strength and impaired functioning of heart, lung, and digestive tract. Persisting malnutrition can be life threatening.

Patients with semi-consciousness, diarrhea, and jaundice have low survival rates. Some children affected with PEM recover completely while others may have to survive with health problems like mental retardation, poor mental growth and development.

How do you Prevent Malnutrition?

Eating a well balanced diet can prevent different types of malnutrition

Breastfeeding a baby for six months is the best way to prevent early childhood malnutrition

Consume foods low in fat and carbohydrates and high in protein

Engage in moderate physical activity at least 4-5 times a week for 30 minutes
